across 1..When an earthquake occurs, it produces shock, or seismic, waves. Two kinds of shock waves can travel through Earth's interior: P (primary) and S (secondary). ... In addition to P- and S-waves, other types of seismic waves can travel along Earth's surface. These are often the most destructive waves in an earthquake.
2.When an earthquake occurs, the elastic energy is released and sends out vibrations that travel in all directions throughout the Earth. These vibrations are called seismic waves. The point within the earth where the fault rupture starts is called the focus or hypocenter
